Development of a cosmetic dye based on the seed of Bixa orellana L. (Bixaceae) and evaluation of its in vitro effect

The purpose of the study was to develop a natural cosmetic dye based on Bixa orellana L. seed (Bixaceae) and to evaluate its effect in vitro. For the development of the cosmetic dye of the seed of Bixa orellana L. two concentrations of the dye obtained were considered (5% and 10%); then, compatibility studies of the raw materials were carried out with the dye under study. The product was packaged and labeled, organoleptic and physicochemical quality controls were carried out, as well as the shelf life of the formulation was determined through the accelerated and long-term stability studies. Finally, the in vitro effect of the cosmetic dye was determined by its application in hair strands. The cosmetic dye made from the seed of Bixa orellana L. at 10% complies with the organoleptic and physicochemical parameters, and remains stable for eighteen months. The in vitro effect showed that the hair strands showed shine and cosmetic quality, permanence of tone after washing and transfer of the dye to the tissue.
